发明名称 Method and apparatus for hermetically sealing a zipper into a reclosable package
摘要 A method and apparatus is disclosed which include a pair of opposed seal bars for the manufacture of reclosable packages. The method and apparatus are particularly adaptable to form fill seal manufacture of reclosable packages. At least one of the opposed seal bars includes a rubberized or otherwise deformable sealing surface. This allows a hermetic seal to be formed across an abrupt transition of thickness of material between the opposed seal bars, such as when a zipper ends adjacent to a side seal in a reclosable bag.
